Specification of Letters Patent.

Patented Dec. 28, 1915.

Application filed January 26, 1914-. Serial No. 814,342.

To all whom it may concern:

Be it known that I, Ronnn'r J. HARRING- TON, a citizen of the United States of America, and resident of Dalton, in the county of Berkshire and State of Massachusetts, have ivented certain new and useful Improvements in Devices for Cleaning Driving-Belts, of which the following is a full, clear, and exact description.

The present invention relates to a device for keeping the belt for driving machinery of various kinds constantly clean, and the invention is characterized by the provision of a revoluble belt cleaner with means in which it is journaled w ereby it is supported in its operative proximity to the running course of the driving belt, and means adapted to derive rotation directly from the belt to be cleaned and which in turn revolubly drives the belt cleaner.

The invention is described in conjunction with the accompanying drawings and is set forth in the claims.

In the drawings :-Figure l is a plan view; Fig. 2 is a side elevation representing my improved belt cleaning device as in its operative relation to the running course of a belt. Fig. 3 is a sectional View taken on line 3-8, Fig. 1. F 1g. 4c is a modification diagram.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings, A represents the support through which the shaft B which carries the revoluble belt cleaner C is rotatively supported. T his support A, as shown in Fig. 3, is made with a tubular extension or boss A The belt cleaner carried at one end portion of the shaft B, may be any of several characters having fitness to the purpose, and to be selectively employed; and as here represented, the revoluble belt cleaner is composed of a plurality of strips of flexible material such as leather or fabric confined by suitable means on the shaft and adapted when the latter is rapidly rotated to have wiping engagements on the surface of the belt adjacent the running course of which the cleaner is mounted in the journal support therefor. As manifest, a rotarybrush may be substituted in place of the cleaner of the type mentioned.

I) represents an arm which at one extremity is made with a circular aperture or bore whereby it is closely fitted externally about the aforementioned tubular boss A of the the arm may be rocked or tilted relatively to the support with tee axis of the latter, and of the shaft 13, as its center of swinging motion. The outer extremity of the said arm D is transversely widened in hub-like formation, as indicated at Z), Fig. l, and

through this hub-like extremity of the arm a shaft E is journaled,the same being always axially parallel with the belt cleaner shaft B. The said shaft E has a roller G affixed on the extremity thereof which is opposite the extremity of the shaft B, carrying the belt cleaner; and said shaft E has at its other extremity a driving wheel H of comparatively large diameter, while on the ex tremity of the shaft B opposite the location of the belt cleaner is a wheel J of diameter very much smaller than that of the wheel H.

A driving connection ll has running connection around the wheels H and J whereby the rotations of the former cause a greater number of rotations of the latter.

In the accompanying drawings, the driving means are represented as ordinary sprocket wheels and sprocket chain, but, as manifest, the equivalent thereof might consist of pulleys and a belt; and in some cases it mightbe deemed more advantageous to employ pulleys H J and a belt L as it would then be permissible to use the belt open or as a crossed belt so that from a given direction of running of the roller carrying shaft E, the belt cleaner shaft could be rotated in the same direction or in the reverse direction as. might in different cases be desired,see Fig. 1-.

M represents anarm, here represented as of a C-shape, the apertured hub portion of which embraces the end portion of the tubular hub extension A of the support A and has confinement thereon by the set screw (Z. Said arm hub prevents displacement of the arm l) in the line of the cleaner shaft axis. Said arm M is extended to adjacent an intermediate portion of the roller carrying arm 1), and it is provided with an offset portion 7 adapted to extend transversely under the arm D and to form a stop to limit the swinging motion of said arm in one direction, as such motion may be imparted by the spring P which has connections with the arms D and M as best shown in Fig. 2.

' device, the support A will be so positioned V as to maintain the roller G carried by the arm D against the belt w'th a yielding pressure permitted and insured by the tiltable character of the arm, and the provision of the spring for its retractile action constantly maintains the peripheral contact notwithstanding that the belt may waver or undulate more or less as it runs.

And it to be pointed out that the arm D =is composed of two sections 9 and it, one of which is long1tudinally adjustable relatively to the other, with means for the confinement of said sections in their adjusted relations such as the provision. of the slot 1' andthe headed and nut provided bolt 7', as

commonly employed for the corresponding purpose in many kinds of mechanism.

Flt is almost unnecessary to explain that the roller G, in peripheral contact against the running belt, deriving rotation therefrom drives the shaft E, which, through the before stated connections, drives the revoluble belt cleaner C.

Ifhe direct support A for the belt cleaner shaft is jointed as shown at on to the extremity of a rod n which is longitudinally as ave'll as ro'tatively adjustable through or in a 'member 0, and which member has an offset portion t which is rotatively and also longitudinally adjustable relatively to a stem or rod a, which latter is adjustably connected with an attachment member or foot :piece w.

The manner of connection or articulation of the last described parts is-such that the device constituting the essential subject matter of this invention may be supported in any situation as required by reason of the particular relation which the course of the belt may have to the primary support for the device; and in some cases the primary support may be a floor, in others the side of the-machine frame; and in others the side or overhead :Wall or post of the building.
